Loosen both engine mounts.

Jack up the engine until the affected one clears

Take off the block mounted portion so you can see the freeze plug

Punch out the old one with an old screw driver or a chisel.

Purchase a rubber universal freeze plug.

Put some permatex around the edge of the new freeze plug.

Insert in the hole and tighten the bolt to secure the freeze plug.

Carefully replace the motor mounts as they will require a little manlipulation.

Caution: Don't not jack the engine on the main front pulley. Use a 2X4 between the jack and oil pan. Put a jack stand under the oil pan with a piece of wood to prevent it punching a hole in the pan and preventing the engine from falling on your sore hands.

Good Luck

Suggested Repair

Loosen both engine mounts and jack the engine, supporting the oil pan with a 2x4 and a jack stand with wood—never the front pulley—until the mount clears. Remove the block-mounted mount portion, punch out the old freeze plug, and install a rubber universal plug with sealant around the edge, tightening its bolt. Carefully reinstall the mounts.

The owner of a 1986 Ford truck asked how to replace a freeze plug behind a motor mount without removing the engine. The expert advised loosening both mounts, jacking the engine off the oil pan with wood for support, removing the mount section, driving out the old plug, and installing a sealed rubber freeze plug before carefully refitting the mounts.
